SMBJ Uni-/Bi-Directional SMD TVS Diodes

Littelfuse SMBJ Uni-/Bi-Directional SMD TVS Diodes protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. The SMBJ diodes feature excellent clamping voltages, low incremental surge resistance, and fast response times in a low-profile package. Littelfuse SMBJ Uni/Bi-Directional SMD TVS Diodes offer protection to I/O interfaces, V_CC bus, and other vulnerable circuits used in telecom, computer, industrial, and consumer electronic applications.
